The Master said, "Yu, have you heard the six words to which are attached six becloudings?" Yu replied, "I have not."

"Sit down, and I will tell them to you.
There is the love of being benevolent without the love of learning - the beclouding here leads to a foolish simplicity. There is the love of knowing without the love of learning - the beclouding here leads to dissipation of mind. There is the love of being sincere without the love of learning - the beclouding here leads to an injurious disregard of consequences. There is the love of straightforwardness without the love of learning - the beclouding here leads to rudeness. There is the love of boldness without the love of learning - the beclouding here leads to insubordination. There is the love of firmness without the love of learning - the beclouding here leads to extravagant conduct."
